High Ammonia and Low pH in the Urine of the Ghost Crab, Ocypode quadrata

The Biological Bulletin, 1994
Nitrogen excreted into the urine (100 mM were found in the urine of laboratory-held Ocypode quadrata, suggesting that this notion might not be applicable to all crustaceans. To address this issue, hemolymph and urine were removed from freshly captured O. quadrata and analyzed for nitrogenous catabolites and major ions. Hemolymph composition was similar

Reed Parrotbill nest predation by tidal mudflat crabs: Evidence for an ecological trap?

Ecosphere, Volume 6, Issue 1, Page 1-12, January 2015., 2015
Understanding the relationships between nesting habitat quality and predation risk is essential for developing appropriate conservation management for threatened species. This is particularly relevant where anthropogenic pressures could decouple the environmental cues used by birds to assess nesting habitat quality from increased predation risk.

Domestic cat predation on Neotropical species in an insular Atlantic Forest remnant in southeastern Brazil

Wildlife Biology, Volume 20, Issue 3, Page 167-175, June 2014., 2014
The domestic cat Felis silvestris catus is considered a potential threat to the native fauna of regions it populates, particularly when it has free access to these areas. Although this problem is known in Brazil, little is known regarding the effects of this species on natural areas.

Anthropogenic Disturbance Threatens the Endangered Tufted Ghost Crab, Ocypode cursor

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT The tufted ghost crab, Ocypode cursor, native to the southeastern Mediterranean and subtropical Atlantic Ocean, is a key bioindicator species, providing valuable insights into the health and stability of sandy beach ecosystems through its population dynamics, behaviour and interactions with the environment. Sandy shores along the Mediterranean

Flooding and a complex predator community drive American oystercatcher nest and chick survival in Virginia

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We investigated low American oystercatcher (Haematopus palliatus) productivity in the Virginia barrier islands, which historically supported high oystercatcher reproductive success. We found that chick survival was lower than nest survival, and that management may need to adapt to address evolving threats from coastal flooding and a multi‐guild ...

Latitudinal Variation in the Timing of Nest Predator Activity Is Habitat Specific

Global Ecology and Biogeography, Volume 34, Issue 1, January 2025.
ABSTRACT Aim The goal of this work was to investigate whether the community of avian nest predators shifts from nocturnal to diurnal with changes in latitude. This hypothesis was formulated 70 years ago, under the rationale that longer day length during the bird breeding season at high latitudes increases opportunities for visual predators.
